What Is Ransomware?

Computer Forensics and Investigation, Cyber First Responder, Encryption, Incident Response, Malware AnalysisOctober 5, 202421Views0Likes0CommentsShare
Ransomware is a type of malicious software (malware) that locks up your computer or encrypts your files, making them inaccessible. It then demands a ransom—usually in cryptocurrency like Bitcoin—in exchange for the key to unlock your files or regain control of your computer. Imagine trying to open a document on your computer, only to be…

Understanding Forensic Data Carving

Computer Forensics and Investigation, CSI Linux, Incident ResponseApril 12, 2024606Views0Likes0CommentsShare
In the digital age, our computers and digital devices hold immense amounts of data—some of which we see and interact with daily, and some that seemingly disappear. However, when files are “deleted,” they are not truly gone; rather, they are often recoverable through a process known in the forensic world as data carving.

Malware analysis is the process of studying and examining malicious software (malware) in order to understand how it works, what it does, and how it can be detected and removed. This is typically done by security professionals, researchers, and other experts who specialize in analyzing and identifying malware threats. There are several different techniques and approaches that can be used in malware analysis, including: Static analysis: This involves examining the code or structure of the malware without actually executing it. This can be done manually or using automated tools, and can help identify the specific functions and capabilities of the malware. Dynamic analysis: This involves running the malware in a controlled environment (such as a sandbox) in order to observe its behavior and effects. This can help identify how the malware interacts with other systems and processes, and what it is designed to do. Reverse engineering: This involves disassembling the malware and examining its underlying code in order to understand how it works and what it does. This can be done manually or using specialized tools. Examples of malware analysis include: Identifying a new strain of ransomware and determining how it encrypts files and demands payment from victims. Analyzing a malware sample to determine its origin, target, and intended purpose. Examining a malicious email attachment in order to understand how it infects a computer and what it does once it is executed. Reverse engineering a piece of malware to identify vulnerabilities or weaknesses that can be exploited to remove or mitigate its effects.

Understanding Dynamic Malware Analysis

Dynamic malware analysis is a technique used to analyze and understand the behavior of a malware sample by running it in a controlled environment and observing its actions. This technique is used to identify the malicious capabilities of a malware sample and to determine the best course of action to mitigate or remove the threat.
